Actually the XTM isn't that much lower than the OS CVRX. I have both engines and have ran both in my MT2 so I am speaking about real world performance not what the magazines rate it at.
The XTM would have done better in my truck if I wasn't limited to the nitro TC3 exhaust.
The main reason I went to the OS is because of the side exhaust and the better selection of pipes.
